Humanely Decreasing O'ahu's Community Cat Population Since 1999
CatFriends started in 1999 with a group of people interested in trying to humanely decrease the numbers of abandoned and feral cats on O'ahu. In 2002 we became a non-profit 501(c)(3) organization.
Our mission is to humanely decrease the abandoned and community (feral) cat population through the widely accepted, non-lethal Trap, Neuter, Return, and Manage (TNRM) methodology. To foster compassion among our island's kama'aina and visitors. To encourage the removal of friendly cats and kittens for fostering, adoption, and to reunite lost felines who have found their way into colonies.
Mass Trapping & Humane Sterilization
We hold public clinics at least once a month. An appointment is needed & can be made through our link located on the spay & neuter clinics tab. Please visit the spay & neuter clinic tab for more info.
Our mass-trapping mode of operation includes training colony caretakers in humane animal trapping, and, with the caretaker's assistance, conducting mass trappings in an effort to sterilize the majority of the cats under their supervision. Once the bulk of the cats have been sterilized, the caretaker must complete the process by trapping and altering the few remaining felines.
Because we operate as an all-volunteer organization, 100 percent of donations to CatFriends are applied towards the costs of humane traps and bait, feline transportation to and from the trapping location, fees associated with microchipping/sterilization, and medical attention felines may require to bring them back to health.
